G7 to hike sanctions on Russia, close to oil price cap deal- U.S. official

G7 leaders will also make an "unprecedented, long-term security commitment to providing Ukraine with financial, humanitarian, military and diplomatic support as long as it takes," including the timely provision of advanced weapons, the White House said in a fact sheet.

The Group of Seven rich democracies will commit on Tuesday to a new package of coordinated actions aimed at increasing pressure on Russia over its war in Ukraine and will finalize plans for a price cap on Russian oil, a senior U.S. official said on Monday. "The dual objectives of G7 leaders have been to take direct aim at (Russian President Vladimir) Putin's revenues, particularly through energy, but also to minimize the spillovers and the impact on the G7 economies and the rest of the world," the official said in a briefing on the sidelines of the annual G7 summit.

Western nations are keen to crank up the pressure on Russia without stoking already soaring inflation that is particularly hurting the global south. The price cap could hit the Kremlin's war chest while actually lowering energy prices. G7 leaders will also make an "unprecedented, long-term security commitment to providing Ukraine with financial, humanitarian, military and diplomatic support as long as it takes," including the timely provision of advanced weapons, the White House said in a fact sheet.
